Hey guys, looking to purchase some Work Brombacher wheel. I know the front will be 19x9.5 with +27 offset, however I see someone has the rear with 19x11 with +12mm with 275 tire and the lip is kind of sticking out. Basically too aggressive. Should I go with the 19x10.5 with +27 offset in the rear or I should go with 19x11 with +21mm in the rear? There is also another option for 19x11 +25mm with A-Disk. Not 100% sure what L-Disk and A-Disk mean. Any suggestions?

Work offers several different pad or "disk" heights to allow for variance in caliper size across different applications. The L disk is the tallest height meaning that it allows for the largest possible brake caliper clearance, while the A disk is a slightly smaller height to give a larger lip size.

The three setups you listed are basically listed in order of how agressive the fitment is. The 10.5 +27 size will be easy to fit, and will allow a variety of tire sizes with no mofication to the quarter panels or camber settings. It is possible to fit the 11 +25 size in the rear without modifying the rear quarters, but you will need to spec tire size and camber very carefully. Finally the 11 +21 size will more than likely require some widening of the quarter panels to fit.
